The majority of cooling systems are based upon vapor-compression refrigeration technology. Its principle has been unchanged for more than a century. Miniaturization and competitiveness have been gained, but there’s still a need of alternative technologies, ...
The Energy Efficiency Directive 2012/27/EU (EED) was released in October 2012 and transposed in June 2014 by Member States. The Directive requires large companies to carry out an energy audit before December 2015, which has to be repeated every 4 years. A ...
In Finland one (and maybe the only) option for large-scale CO2 capture, utilisation and storage (CCUS) seems to be mineralisation, also known as mineral carbonation. Mineral resources in the country should allow for the fixation of quite a few Gt CO2. The ...

Networked systems are composed of interconnected nodes that work collaboratively to maximize a given overall utility function. Typical examples of such systems are wireless sensor networks (WSNs) and participatory sensing systems: sensor nodes, either stat ...
The improvement of the efficiency of vehicle energy systems promotes an active search to find innovative solutions during the design process. This requires more accurate modeling of complex systems, which offers new ways to improve the design efficiency of ...
Horizon 2020 is the largest EU Research and Innovation programme to date. The European fusion research programme for Horizon 2020 is outlined in the "Roadmap to the realization of fusion energy" and published in 2012 [1]. As part of it, the European Fusion ...
The development of integrally cast turbine airfoils allows the production of narrow impingement channels in a double-wall configuration, where the coolant is practically injected within the wall of the airfoil providing increased heat transfer capabilities ...
This paper examines the applicability of a triple layer of thermochromic liquid crystals on the evaluation of local heat transfer coefficients using the transient liquid crystal measurement technique. The experiments were carried out in a narrow impingemen ...

The present report describes the method used for the computation and integration of the energy system which has been built within this semester. All the supplying energy technologies , which have been taken into account are presented. The fundamental equat ...
The world energy consumption has dramatically increased since the end of the World War II. The main share of this energy comes from fossil fuel combustion. The worldwide domestic sector consumes about 30% of the global energy supply and the biggest share o ...
